Upgrading to a New Software Release

For information about upgrading to a new software release, see the Cisco IOS Software Release 11.3 Upgrade Paths and Packaging Simplification  product bulletin located on CCO at:

Service & Support: Product Bulletins: Software

Under Cisco IOS 11.3, click on Cisco IOS Software Release 11.3 Upgrade Paths (#703: 12/97).

This product bulletin does not include information specific to Cisco IOS Release 11.3 T, but provides general upgrade information that may apply to Cisco IOS Release 11.3 T.

Microcode and Modem Code Software

Microcode software images are bundled with the system software image---with the exception of the Channel Interface Processor (CIP) microcode (all system software images). Bundling eliminates the need to store separate microcode images. When the router starts, the system software unpacks the microcode software bundle and loads the proper software on all the interface processor boards.

Note You could have received a later version of modem code than the one bundled with the Cisco IOS software. The modem code in Flash memory is mapped to the modems. Unless you fully understand how Cisco IOS software uses modem code, it is important to keep the factory configuration.

The modem code release notes and configuration information are on CCO and the Documentation CD-ROM:

1This feature is offered in the Basic feature set.
2This feature is offered in the encryption feature sets which consist of IPSec 56-bit (Plus IPSec 56) data encryption feature sets.

Caution
Cisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay due to United States government regulations. When applicable, you must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

New and Changed Information

The following sections list the new features supported by the Cisco 3600 series in Cisco IOS Release 11.3 T. For more information about these features, see the "Related Documentation" section.

New Features in Release 11.3(7)T through Release 11.3(11)T

There are no new hardware or software features supported by the Cisco 3600 series in Cisco IOS Release 11.3(7)T through Release 11.3(11)T.

New Software Feature in Release 11.3(6)T

The following new software feature is supported by the Cisco 3600 series in Cisco IOS Release 11.3(6)T and later releases.

Cisco Dial-Out Client

The Cisco Dial-Out Client allows modems connected to a router to be used transparently for dial-out from a LAN users desktop (using Microsoft Windows). This feature allows users to call the Internet and bulletin board services from their desktop, and allows faxing from the PC, using programs such as Winfax Pro.

The first version of Cisco Dial-Out Client has been available for some time now, supporting the Cisco 3600 series with asynchronous and sync/async network modules, connected to external data/fax modems. Now, in tandem with MICA Portware 2.5.1.0, V2 of the Cisco Dial-Out Client is available, adding support for the Cisco 3600 series integrated MICA modems for both dial-out and fax-out applications. This support allows the Cisco 3600 series with digital modems (using Cisco IOS Release 11.3(6)T and later to act as a dial-out server for LAN-attached PCs in branch offices.

New Software Feature in Release 11.3(5)T

The following new software feature is supported by the Cisco 3600 series in Cisco IOS Release 11.3(5)T and later releases.

V.90

56-kbps modem firmware (V.90) is available for the Cisco 3600 series beginning in Cisco IOS Release 11.3(5)T. V.90 is the new standard for 56k modem communication, and is an evolution from the older K56Flex and X2 protocols. This firmware update will allow 56K-enabled client modems to archive the maximum connect speeds possible using this new technology. Benefits include faster Web access, faster file download, and improved multimedia support. This firmware version
is 2.5.1.0.

New Hardware Feature in Release 11.3(4)T

The following new hardware feature is supported by the Cisco 3600 series in Cisco IOS Release 11.3(4)T and later releases.

Eight New Enhanced PRI Network Modules

The following eight Enhanced PRI network modules were added to the Cisco 3600 series:

The Cisco 3600 series team is pleased to announce new enhanced versions of PRI Network Modules, now available with a integrated 10/100BaseTX Ethernet port. These network modules provide greater versatility, allowing for better slot efficiency and increased port densities when utilized in the Cisco 3600 series with Cisco IOS Release 11.3(4)T and later.

These new network modules, when combined with the Digital Modem network modules, provide hybrid ISDN/Analog dial access capabilities for the first time on the Cisco 3620, lowering the entry price for 1 PRI with 24/30 Digital Modems solution.

This network module can also be utilized in a Cisco 3640, allowing support for up to 8 PRI in a 2RU chassis.

New Hardware Features in Release 11.3(3)T

The following new hardware features are supported by the Cisco 3600 series in Cisco IOS Release 11.3(3)T and later releases.

1-Port ATM-25 Network Module for the Cisco 3600 Series

The 1-port asynchronous transfer mode (ATM-25) network module provides connectivity to an external asynchronous digital subscriber line (ADSL) modem for Cisco series 3600 routers. This network module provides ATM traffic shaping for use with ADSL uplink speeds and protocol support for permanent virtual circuit (PVC) environments. This network module provides full support for multiprotocol encapsulation over ATM Adaptive Layer 5(RFC 1483), classic IP over ATM encapsulation (RFC 1577), and Cisco Point-to-Point Protocol (PPP) over ATM.

In the online feature description, Figure 1 shows the 1-port ATM-25 network module in a typical ADSL application environment. In this example, the network module and the associated Cisco 3640 router provide ATM connectivity to the ADSL modem and provide traffic shaping and protocol encapsulation for the downstream LAN clients.

1-Port High Speed Serial Interface (HSSI) Network Module

The Cisco 3600 series 1-port high-speed serial interface (HSSI) network module provides full-duplex connectivity at Synchronous Optical Network (SONET) OC-1/STS-1 (51.840 Mhz), T3 (44.736 MHz), and E3 (34.368 MHz) rates in conformance with the EIA/TIA-612 and EIA/TIA-613 specifications. The actual rate of the interface depends on the external data service unit (DSU) and the type of service to which it is connected. This 1-port HSSI network module can reach speeds of up to 52 Mbps in unidirectional traffic with 1,548-byte packets and 4,250 packets per second. Asynchronous Transfer Mode (ATM), ATM with Data Exchange Interface (DXI), High-Level Data Link Control (HDLC), Point-to-Point Protocol (PPP), Frame Relay, and Switched Multi-Megabit Data Service (SMDS) WAN services are all fully supported.

The 1-Port HSSI network module provides the following benefits:

T1 CAS Support for the Cisco 3640 Digital Modem Network Module

The Digital Modem Network Module for the Cisco 3640 is a high-density digital network module containing, 6, 12, 18, 24, or 30 digital (MICA) modems. These modems, along with the T1 (or E1) port module, provide a direct digital connection to an Integrated Services Digital Network (ISDN) Primary Rate Interface (PRI) channel. The T1 CAS feature enables these network modules to support voice call transmission using channelized T1 lines (CT1) with channel associated signaling (CAS).

CAS is a form of signaling used on a T1 line. With CAS, a signaling element is dedicated to each channel in the T1 frame. This type of signaling is sometimes called Robbed Bit Signaling (RBS) because a bit is taken out (or robbed) from the user's data stream to provide signaling information to and from the switch. The T1 CAS feature enables the modems on the Digital Network Modem Module to receive and transmit incoming and outgoing call signaling (such as on-hook and off-hook) through each T1 controller that is configured for a channelized T1 line.

New Software Features in Release 11.3(3)T

The following new software features are supported by the Cisco 3600 series in Cisco IOS Release 11.3(3)T and later releases.

IBM SUPPORT:

RIF Passthrough in DLSw+

By default, DLSw+ terminates the RIF for Token Ring, terminates the LLC for all media types and forwards only data across a WAN with DLSw+ and TCP/IP headers. The RIF is a field in source-route bridged frames that indicates the SRB path the frame should take when traversing a Token Ring network. In the case of an explorer packet, the RIF is a field of the source-route bridged frame that indicates the SRB path that the SRB explorer has traversed so far. The RIF is limited to seven hop counts by the IBM standards. Because DLSw+ terminates the RIF at the virtual ring, the network's scalability increases because the hop count of the packet starts over, and the packet can traverse seven additional hops. Also, RIF termination simplifies network design because ring numbers no longer have to be unique throughout an entire enterprise.

However, some environments do not function properly if the RIF is terminated. For that reason, DLSw+ now supports the RIF Passthrough feature, in which the entire source-route bridged path appears in the RIF.

MANAGEMENT:

VPDN MIB and Sys Log Facility

The Virtual Private Dialup Network (VPDN) Management Information Base (MIB) feature is intended to support all the tables and objects defined in "Cisco VPDN Management MIB" for the user sessions of the VPDN features. There are a number of commands which provide information and statistics through the Command Line Interface (CLI) but not Simple Network Management Protocol (SNMP); the Cisco VPDN MIB has been created to satisfy the need to provide information and statistics through SNMP.

SECURITY:

Additional Vendor-Proprietary RADIUS Attributes

Remote Authentication Dial-In User Server (RADIUS) is an access server authentication, authorization, and accounting protocol originally developed by Livingston, Inc. Although an Internet Engineering Task Force (IETF) draft standard for RADIUS specifies a method for communicating vendor-proprietary information between the network access server and the RADIUS server, some vendors have extended the RADIUS attribute set in a unique way. In this release, Cisco IOS software introduces support for additional vendor-proprietary RADIUS attributes.

Users who have implemented security solutions using a vendor-proprietary implementation of RADIUS can now integrate Cisco access routers into their networks more easily.

For a complete list of supported IETF and vendor-proprietary RADIUS attributes, refer to the "RADIUS Attributes" appendix in the Cisco IOS Release 11.3 Security Configuration Guide.

Automated Double Authentication

The automated double authentication feature enhances the existing double authentication feature.

Previously, with the existing double authentication feature, a second level of user authentication is achieved when the user Telnets to the network access server or router and enters a username and password. Now, with automated double authentication, the user does not have to Telnet anywhere but instead responds to a dialog box that requests a username and password or PIN.

For information about the existing double authentication feature, refer to the "Configuring Authentication" chapter of the Cisco IOS Release 11.3 Security Configuration Guide.

Certificate Authority Interoperability

Certificate Authority (CA) interoperability is provided in support of the IP Security (IPSec) standard. CA interoperability permits Cisco IOS devices and CA devices to communicate so that your Cisco IOS device can obtain and use digital certificates from the CA. Although IPSec can be implemented in your network without the use of a CA, using a CA provides manageability and scalability for IPSec.

For background and configuration information for IPSec, see the "IPSec Network Security"  feature documentation.

IPSec Network Security

IPSec is a framework of open standards developed by the Internet Engineering Task Force (IETF).

IPSec provides security for transmission of sensitive information over unprotected networks such as the Internet. IPSec acts at the network layer, protecting and authenticating IP packets between participating IPSec devices ("peers") such as Cisco routers.

IPSec provides the following network security services:

With IPSec, data can be transmitted across a public network without fear of observation, modification, or spoofing. This enables applications such as virtual private networks (VPNs), extranets, and remote user access.

IPSec services are similar to those provided by Cisco Encryption Technology, a proprietary security solution introduced in Cisco IOS Software Release 11.2. (The IPSec standard was not yet available at Release 11.2.) However, IPSec provides a more robust security solution, and is standards-based.

Internet Key Exchange Security Protocol

ISAKMP/Oakley is a key management protocol which is used with the IPSec standard. IPSec is an IP security feature that provides robust authentication and encryption of IP packets.

IPSec can be configured without ISAKMP/Oakley, but ISAKMP/Oakley enhances IPSec by providing additional features, flexibility, and ease of configuration for the IPSec standard.

ISAKMP/Oakley is a hybrid protocol which implements the Oakley key exchange inside the ISAKMP framework.

MS-CHAP Support

Microsoft Challenge Handshake Authentication Protocol (MS-CHAP) is the Microsoft version of CHAP. Like the standard version of CHAP, MS-CHAP is used for PPP authentication; in this case, authentication occurs between a PC using Microsoft Windows NT or Microsoft Windows 95 and a Cisco router or access server acting as a network access server (NAS).

MS-CHAP differs from the standard CHAP as follows:

Depending on the security protocols you have implemented, PPP authentication using MS-CHAP can be used with or without Authentication, Authorization, and Accounting (AAA) security services. If you have enabled AAA, PPP authentication using MS-CHAP can be used with both TACACS+ and RADIUS.

Two new vendor-specific RADIUS attributes (IETF Attribute 26) were added to enable RADIUS to support MS-CHAP. For a complete list of supported IETF and vendor-proprietary RADIUS attributes, refer to the "RADIUS Attributes" appendix in the Cisco IOS Release 11.3 Security Configuration Guide.

Named Method Lists for AAA Authorization and Accounting

In earlier Cisco IOS releases, only named authentication method lists were supported under Cisco's Authentication, Authorization, and Accounting (AAA) network security services. With Cisco IOS Release 11.3(4)T, AAA has been extended to support both authorization and accounting named method lists. Named method lists for authorization and accounting function the same way as those for authentication. They allow you to define different methods for authorization and accounting and apply those methods on a per-interface or per-line basis.

WAN OPTIMIZATION:

Always On/Dynamic ISDN (AO/DI)

Always On/Dynamic ISDN (AO/DI) is an on-demand service that optimizes the use of an existing Integrated Services Digital Network (ISDN) signaling channel (D channel) to transport X.25 traffic. The X.25 D channel call is placed from the subscriber to the packet data service provider. Multilink and TCP/IP protocols are encapsulated within the X.25 logical circuit carried by the D channel. The bearer channels (B channels) use the Multilink protocol without the standard Q.922 and X.25 encapsulations and invoke additional bandwidth as needed. AODI takes full advantage of existing packet handlers at the central office by using an existing D channel to transport the X.25 traffic. The link associated with the X.25 D channel packet connection is used as the primary link of the Multilink protocol. The D channel is a connectionless, packet oriented link between the Customer Premise Equipment (CPE) and the central office. Since the D channel is always available, it is possible to in turn offer "always available" services. On-demand functionality is achieved by using the B channels to temporarily boost data throughput and are disconnected after use.

WAN SERVICES:

Microsoft Point-to-Point Compression (MPPC)

Microsoft Point-to-Point Compression (MPPC) is a scheme used to compress Point-to-Point Protocol (PPP) packets between Cisco and Microsoft client devices. The MPPC algorithm is designed to optimize processor and bandwidth utilization in order to support multiple simultaneous connections. The MPPC algorithm uses a Lempel-Ziv (LZ) based algorithm with a continuous history buffer, called a dictionary.

Multiple ISDN Switch Types

The Multiple ISDN Switch Types feature allows you to configure more than one ISDN switch type per router. You can apply an ISDN switch type on a per interface basis, thus extending the existing global isdn switch-type command to the interface level. This allows Basic Rate Interfaces (BRI) and Primary Rate Interfaces (PRI) to run simultaneously on platforms that support both interface types.

The isdn tei command is also extended to the interface level. Terminal endpoint negotiation (TEI) determines when Layer 2 is activated (power-up or first-call).

National ISDN Switch Types for Basic Rate and Primary Rate Interfaces

National ISDN Switch Types for Basic Rate and Primary Rate Interfaces introduces changes to ISDN switch types for Primary Rate Interfaces (PRI) and Basic Rate Interfaces (BRI) as follows:

Note The command parser will still accept the following switch types: basic-nwnet3, vn2, and basic-net3; however, when viewing the NVRAM configuration using either the show running configuration or write terminal command, the basic-net3 or vn3 switch types are displayed respectively.

X.25 over ISDN D-Channel

Basic Rate Interface (BRI) is an Integrated Systems Digital Network (ISDN) interface, and it consists of two B channels (B1 and B2) and one D channel. The B channels are used to transfer data, voice, and video. The D channel controls the B channels.

ISDN uses the D channel to carry signal information. ISDN can also use the D channel in a BRI to carry X.25 packets. The D channel has a capacity of 16 kbps, and the X.25 over D channel can use up to 9.6 kbps.

You can set the parameters of the X.25-over-D-channel interface without disrupting the original ISDN interface configuration. In a normal ISDN BRI interface, the D and B channels are bundled together and represented as a single interface. The original BRI interface continues to represent the D, B1, and B2 channels.

Because some end-user equipment uses static terminal endpoint identifiers (TEIs) to access this feature, static TEIs are supported. The dialer recognizes the X.25-over-D-channel calls and initiates them on a new interface.

X.25 traffic over the D channel can be used as a primary interface where low-volume, sporadic interactive traffic is the normal mode of operation. Supported traffic includes IPX, AppleTalk, transparent bridging, XNS, DECnet, and IP.

New Hardware Feature in Release 11.3(2)T

The following new hardware feature is supported by the Cisco 3600 series in Cisco IOS Release 11.3(2)T and later releases.

Digital Modem Network Module for the Cisco 3640

The Digital Modem Network Module for the Cisco 3640 is a high-density digital network module containing 6, 12, 18, 24, or 30 V.34+ (28.8 kbps) digital (MICA) modems. These modems provide a direct digital connection to an Integrated Services Digital Network (ISDN) Primary Rate Interface (PRI) channel. This digital modem network module allows you to support a mix of both digital (ISDN) and POTS analog modem calls over a single digital network interface.

Depending on the modem license you purchase with your Cisco 3640, the modems on the Digital Modem Network Module are either manageable or not manageable by Cisco IOS software commands. Manageable modems support the one out-of-band feature, which is used for gathering modem performance statistics and transmitting attention (AT) commands. If the license you purchase includes this modem management capability, you can use the modem management commands to gather call statistics and upgrade modem firmware for large modem pools.

New Software Features in Release 11.3(2)T

The following new software features are supported by the Cisco 3600 series in Cisco IOS Release 11.3(2)T and later releases.

Dialer Watch

Dialer Watch is a backup feature that integrates dial backup with routing capabilities. Prior dial backup implementations used the following conditions to trigger backup:

Prior backup implementations may not have supplied optimum performance on some networks, such as those using Frame Relay multipoint subinterfaces or Frame Relay connections that do not support end-to-end LMI.

Dialer Watch provides reliable connectivity without relying solely on defining interesting traffic to trigger outgoing calls at the central router. Dialer Watch uses the convergence times and characteristics of dynamic routing protocols. Integrating backup and routing features enables Dialer Watch to monitor every deleted route. By configuring a set of watched routes that define the primary interface, you are able to monitor and track the status of the primary interface as watched routes are added and deleted. Monitoring the watched routes is done in the following sequence:

    1. Whenever a watched route is deleted, Dialer Watch checks to see if there is at least one valid route for any of the watched IP addresses defined.

    2. If there is no valid route, the primary line is considered down and unusable.

    3. If there is a valid route for at least one of the defined watched IP addresses, and if the route is pointing to an interface other than the backup interface configured for Dialer Watch, the primary link is considered up.

    4. In the event that the primary link goes down, Dialer Watch is immediately notified by the routing protocol and the secondary link is brought up.

    5. When the secondary link is up, at the expiration of each idle timeout, the primary link is rechecked.

    6. If the primary link remains down, the idle timer is indefinitely reset.

    7. If the primary link is up, the secondary backup link is disconnected. Additionally, a disable timer can be set to create a delay for the secondary link to disconnect, after the primary link is reestablished.

MS Callback

The MS Callback feature provides client-server callback services for Microsoft Windows 95 and Microsoft Windows NT clients. MS Callback supports the Microsoft Callback Control Protocol (MSCB). MSCB is Microsoft's proprietary protocol that is used by Windows 95 and Windows NT clients. MS Callback supports negotiated PPP Link Control Protocol (LCP) extensions initiated and agreed upon by the Microsoft client. MS Callback is added to existing PPP Callback functionality. Therefore, if you configure your Cisco access server to perform PPP Callback using Cisco IOS Release 11.3(2)T or later, MS Callback is automatically available.

MS Callback supports AAA security models using a local database or AAA server.

MSCB uses LCP callback options with suboption type 6. The Cisco MS Callback feature supports clients with a user-specified callback number and server specified (preconfigured) callback number.

MS Callback does not affect non-Microsoft machines that implement standard PPP LCP extensions as described in RFC 1570. In this scenario, MS Callback is transparent.

PIM Version 2

Protocol-Independent Multicast (PIM) Version 2 includes the following improvements over PIM Version 1:

PIM Version 1, together with the Auto-RP feature, can perform the same tasks as the PIM Version 2 BSR. However, Auto-RP is a standalone protocol, separate from PIM Version 1, and is Cisco proprietary. PIM Version 2 is a standards track protocol in the Internet Engineering Task Force (IETF).

Cisco's PIM Version 2 implementation allows good interoperability and transition between Version 1 and Version 2. You can upgrade to PIM Version 2 incrementally. PIM Versions 1 and 2 can be configured on different routers within one network. Internally, all routers on a shared media network must run the same PIM version. Therefore, if a PIM Version 2 router detects a PIM Version 1 router, the Version 2 router downgrades itself to Version 1 until all Version 1 routers have been shut down or upgraded.

PIM uses the BSR to discover and announce RP-set information for each group prefix to all the routers in a PIM domain. This is the same function accomplished by Auto-RP, but the BSR is part of the PIM Version 2 specification. The BSR mechanism interoperates with Auto-RP.

To avoid a single point of failure, you can configure several candidate BSRs in a PIM domain. A BSR is elected among the candidate BSRs automatically; they use bootstrap messages to discover which BSR has the highest priority. This router then announces to all PIM routers in the PIM domain that it is the BSR.

Routers that are configured as candidate RPs then unicast to the BSR the group range for which they are responsible. The BSR includes this information in its bootstrap messages and disseminates it to all PIM routers in the domain. Based on this information, all routers will be able to map multicast groups to specific RPs. As long as a router is receiving the bootstrap message, it has a current RP map.

DRP Server Agent Enhancements

DRP Server Agent Enhancements---The DRP Server Agent is a Director Response Protocol (DRP) server application based on UDP for use only with Distributed Director. The DRP Server Agent will provide the following additional functionality:

Release 11.3(3a) and all subsequent releases of Cisco IOS Release 11.3 software include the fix for this caveat.

Encryption Images

Encryption images are available in this Cisco IOS Release 11.3(4)T and later 11.3 T releases. See Table 1, "Memory Requirements for the Cisco 3600 Series".

New TACACS+ Attribute-Value (AV) Pair

A new authorization feature was added in Cisco IOS Release 11.3(1) that allows for separate configuration and authorization of Multilink PPP. This can cause MLP authorization to fail in TACACS+ servers that do not include the relevant authorization permissions in the configuration.

For TACACS+, the following attribute-value (AV) pair should be added for all users who are allowed to negotiate Multilink PPP:

service = ppp protocol = multilink {

Bridge Multicast-Source Command

As of Cisco IOS Release 11.3(2)T, the bridge multicast-source command is no longer available. This command was removed to comply with the source-route transparent bridging (SRT) implementation.

Missing Source-Route Bridging Commands

Due to a production problem, many source-route bridging commands were omitted from the printed version of the Cisco IOS Software Command Summary (78-4746-01). For complete documentation of all source-route bridging commands refer to the Bridging and IBM Networking Command Reference (78-4743-01). You may also obtain the most current documentation on the Documentation CD-ROM or Cisco Connection Online (CCO).

The WWW version of CCO provides richly formatted documents with photographs, figures, graphics, and video, as well as hyperlinks to related information.

You can reach CCO in the following ways:

Documentation CD-ROM

Cisco documentation and additional literature are available in a CD-ROM package, which ships with your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is updated monthly. Therefore, it may be more current than printed documentation. To order additional copies of the Documentation CD-ROM, contact your local sales representative or call customer service. The CD-ROM package is available as a single package or as an annual subscription. You can also reach Cisco documentation on the World Wide Web at http://www.cisco.com, http://www-china.cisco.com, or http://www-europe.cisco.com.

If you are reading Cisco product documentation on the World Wide Web, you can submit comments electronically. Click Feedback in the toolbar, select Documentation, and click Enter the feedback form. After you complete the form, click Submit to send it to Cisco. We appreciate your comments.
